Weather Station Arudino

1. Download the code from https://github.com/jaroslavhuss/uuiot/blob/master/weatherstation/sketch_feb24a/sketch_feb24a.ino and flash it on the Arduino
2. It will require a library for DHT22 - just google it and upload it along with the code.

Gateway

1. I am using RPi Ubuntu, u need to have nodejs installed

2. I recommend to intall everything in a root folder in order to avoid problem with paths

3. type npm init -y

4. type touch weatherimporter.js

5. type npm install dontenv axios node-cron node-red

6. Into weatherimporter.js place a code from https://github.com/jaroslavhuss/uuiot/blob/master/gateway/weatherimporter.js

I forgot to mention - you need to also touch .env and place credentials there as followed:

GW_USERNAME = Name of your GW (u have created this in cloud)
GW_PASSWORD = Password to the GW (u have created this as well)

Now we need to setup node-red

7. Open console on RPi and type node-red
8. this will start a local server. To access it you need to know your RPi IP address - mine runs on http://10.0.1.29:1880/
9. You have to import a json file into node-red UI from https://github.com/jaroslavhuss/uuiot/blob/master/gateway/node-red.json
10. Do not forget to deploy changes done on node-red

How to run the script on boot?

The best way I found is described here: https://nodered.org/docs/faq/starting-node-red-on-boot

Basically you need to type just this:

1. sudo npm install -g pm2
2. navigate to the folder where you downloaded the project (weatherimporter.js)
3. Hit pm2 start weatherimporter.js --node-args="--max-old-space-size=128" -- -v
4. Update the list of tasks pm2 save
5. Lastyl hit pm2 startup - this will spill the command for @boot
6. Just take that fakin command and place it into console
7. Hit sudo reboot and u are fakin done!
